It consists of time base circuit, integrated block and peripheral components.
It has beautiful sound quality, easy installation, low cost and low power consumption.
Its working voltage is DC3V-12V.
Typically powered by a 9V laminated battery.
The higher the voltage, the louder the sound.
Since the speakers are not in the box, the panning at the front and back of the board cancels out the volume, and the volume is lower.
You can load it into a carton to increase the volume.
